The first-grader was pulled by a Jefferson County Public Schools bus on Friday when her backpack got caught in the door.

Louisville Metro Police spokesman Dwight Mitchell says the female driver had stopped to let the girl off at her babysitter’s house and closed the door on her backpack. The driver didn’t notice the girl was being dragged until a car behind the bus sped up with its horn blaring.

The district said on Monday that the driver has been suspended without pay pending an investigation.
